My simulation runs slow although there are less than 200 vehicles in the network. Sometimes it also looks as if the simulation speed varies a lot during one simulation. What could be the reason?
Check the following:
- Delete all speed distributions that are not used in the simulation (especially those with higher speeds).
- Check priority rule parameters. Avoid long gap times or headways in combination with multiple look-back paths.
- Multiple look-back paths can also be avoided by reducing the driving behavior parameter 'Look back distance' for all links/connectors where applicable (e.g. at parking lots where each space is modeled on an individual link - such as for diagonal or perpendicular parking).
- At roundabouts, reduce the number of short connectors (that are used for routing purposes).
